SIGNAL FIELDS IN A HIGH EFFICIENCY WIRELESS LOCAL AREA NETWORK (WLAN) DATA UNIT

摘要

A first signal field to be included in a preamble of a physical layer (PHY) data unit is generated. The first signal field includes formatting information for a second signal field to be included in the PHY data unit. The formatting information includes an indication of a number of orthogonal frequency division multiplexing (OFDM) symbols in the second signal field. The second signal field is generated according to the formatting information in the first signal field. The second signal field includes formatting information for a data portion of the PHY data unit. The data portion is generated according to the formatting information in the second signal field. The preamble is generated to include at least the first signal field and the second signal field, The PHY data unit is generated to include the preamble and the data portion.

主权项

1. A method for generating a physical layer (PHY) data unit for transmission via a communication channel, the method comprising:
generating a first signal field to be included in a preamble of the PHY data unit, wherein the first signal field includes formatting information for a second signal field to be included in the PHY data unit, wherein the formatting information includes an indication of a number of orthogonal frequency division multiplexing (OFDM) symbols in the second signal field; generating the second signal field according to the formatting information in the first signal field, wherein the second signal field includes formatting information for a data portion of the PHY data unit; generating the data portion according to the formatting information in the second signal field; and generating the preamble to include at least the first signal field and the second signal field; and generating the PHY data unit to include the preamble and the data portion.
